Sectors activating scripts (Solved)

Hey folks. Just curious if there is any way to do this? I just want to display a message once when the player is present in a particular sector, and I'm not sure which script does this. As far as I know, it seems like linedefs and things can activate scripts but I can't find out on the zdoomwiki how to make sectors activate scripts. Thanks in advance

Nevermind! I finally found it after literally going through every action special. http://zdoom.org/wiki/Classes:SecActEnter

ZDoom has some special actors which you can place in a sector, which can then be set to trigger their action based upon various things that happen in that sector. For the most part, you can set these to activate a script much like any other Thing. The specific actor that you probably want in this case is detailed here.

Thanks Mithran, I just found it a couple seconds ago and I'm implementing it right now.
